BENEATH Punjab’s lush green fields, a reservoir is running dry—and nobody is counting the drops. For decades, the province’s subterranean aquifers have been the unsung lifeline of our agrarian economy.

Today, policy paralysis, technological change and institutional neglect are draining these hidden reserves at a breakneck pace, leaving behind a toxic legacy of salinity and scarcity. Pakistan is the world’s third-largest user of groundwater for irrigation, with 73% of its agricultural footprint relying directly or indirectly on it. Of the 68 billion cubic meters (bm3) extracted annually, Punjab alone accounts for 90% of the 60 bm3 pumped for irrigation. Put simply, we are extracting groundwater 142% faster than nature can replenish it. The latest data from the Water Resources Zone (WRZ) of the Punjab Irrigation Department (PID) paints a grim picture. Punjab’s groundwater table is falling by 0.5 to 1.0 meters annually. Pre- and post-monsoon piezometer readings show annual declines of 1.81ft in Pakpattan, 1.72ft in Okara and 1.52ft in Multan. In volumetric terms, Okara and Rahim Yar Khan alone lose about 4.15 and 4.08 million acre-feet (MAF) of groundwater each year. Overall, Punjab’s groundwater withdrawals have exceeded 53 MAF—almost matching the province’s entire allocated canal surface water share of 56 MAF.

How did we get here? The answer lies in a paradoxical twist of technology. In 1960, Punjab had a mere 4,500 tubewells; today, that number........
